Embodiment Construction

[0027] The present invention will be further described below in conjunction with accompanying drawing.

[0028] see Figure 1 to Figure 3 , the universal circuit breaker of the present invention that can be plugged with a live plug controller includes a circuit breaker housing, and the housing is provided with a contact system, three transformers 11 and a controller with a power supply. The housing includes a base 1 and a mask 6, and the control The device includes a controller base 2, a controller upper box 5, a tripping electromagnet 25 and a circuit board 4 with circuit elements. The controller base 2 is fixedly connected to the base 1, and the circuit board 4 is fixed on the controller. On the upper box body 5, the controller base 2 is provided with a bus plug connector 22, and the controller upper box body 5 is correspondingly provided with a bus plug interface 41 that is plugged and matched with the bus plug connector 22, and the bus plug interface 41 is connected to the...

Abstract

The invention relates to a universal circuit breaker with a hot-pluggable controller, comprising a breaker shell, a contact system, a mutual inductor, and a controller are arranged in the shell, the controller comprises a controller pedestal, a controller upper case, a tripping electromagnet, and a circuit board provided with circuit components, the tripping electromagnet is arranged on the controller pedestal, the controller pedestal is fixedly connected with the base, the circuit board is fixed on the controller upper case, a bus connector plug is arranged on the controller pedestal, a bus interface is arranged correspondingly on the controller upper case to be in an insertion fit with the bus connector plug, the bus interface is connected with the circuit board, the controller pedestal and the controller upper case are removablely and separately connected. When a controller needs to be replaced by the circuit breaker, the controller can be replaced by the circuit breaker without breaking the main current of the whole circuit breaker, and only the controller upper case is removed for replacing the controller. The maintenance and removal are more convenient.

Description

technical field [0001] The invention relates to a universal circuit breaker with a live pluggable controller. Background technique [0002] During the use of the universal circuit breaker, because the electronic components in the controller are relatively easy to age, the service life is relatively short. In order to ensure the safety of use, some competent departments will stipulate that the controller of the universal circuit breaker must be replaced after a certain number of years of use. [0003] However, due to the structure of the existing universal circuit breaker, when replacing the controller, the main circuit of the circuit breaker must be powered off, and then the controller can be replaced. Obviously, this will bring great inconvenience to the entire power supply system. Contents of the invention [0004] The object of the present invention is to overcome the defects of the prior art and provide a universal circuit breaker capable of plugging and unplugging t...
